About the network this uses, is this a serial network, like a can bus or rs485? If so, it could be easy as well as interesting to see what the protocol looks like with a serial monitor or oscilloscope.

[@IanScottJohnston]

From Wikipedia......LonWorks or Local Operating Network is an open standard for networking platforms specifically created to address the needs of control applications. The platform is built on a protocol created by Echelon Corporation for networking devices over media such as twisted pair, power lines, fibre optics, and wireless.

I thought you've send all of your capacitors to New Zeeland

[@IanScottJohnston]

It would seem some fell out of the parcel when I was packing them up!

[@jaycee1980]

Interesting failure... the capacitors looked like they were Panasonic ones, usually very good ! it could have been running somewhere hot, I suppose...

[@TheDefpom]

It’s always a crapacitor

[@fredflintstone1]

I hope you don't need a capacitor to repair this item as you seem to have sent them all overseas to the otherside of the world🙂

[@IanScottJohnston]

Oh!......yeah, forgot about that dang!

[@TheEmbeddedHobbyist]

@@IanScottJohnston i hear that Scott's got quite a lot of caps now.
